Patent CA-2306614-A1 (CA)
Inventor: PHANG WAYNE M
IPC: H04B1/40
Filed: 2000-04-26
Abstract: A receiver (100) provides dual band features by providing two signal paths (106, 108) off an antenna (102), one for UHF operation (106) and one for VHF operation (108). The two signals paths (106, 108) feed into a single broadband input (124) of a direct conversion receiver (114). The UHF path (106) utilizes UHF front end circuitry (110) while the VHF path (108) is implemented with a loading/isolator circuit (120) and a matching circuit (122). The loading/isolator circuit (120) loads the antenna (102) and isolates UHF signals while the matching circuit (122) provides a match between the loading isolator circuit (120) an the direct conversion receiver (114). Selectable matching circuitry (126, 128) and selectable VCO circuitry (132, 134) configures the direct conversion receiver for the UHF or VHF mode of operation.

Patent CA-2328086-A1 (CA)
Title: Personal watercraft carrier
Inventor: KAMMINGA BRUCE L
IPC: B60P3/10
Filed: 2000-12-13
Abstract: The invention relates to a personal watercraft carrier for transporting personal watercraft such as jet skis, wave runners and the like, into and out of the water. The personal watercraft carrier has a conventional carrier frame, which includes rail supports for the watercraft, and a tongue having a handle for pushing or pulling the carrier, and is supported by one or more axles, which rotatably mount large-surface wheels. The wheels support the weight of the watercraft and carrier while traveling over soft terrain e.g. sand. The wheels are constructed so that the carrier as a whole has neutral or negative-buoyancy. As a result of the neutral or negative-buoyancy of the carrier, the carrier can drop away as the depth of the water increases, thus enabling the watercraft to be easily removed from the carrier. Similarly, the carrier can be positioned below the surface of the water for retrieval of the watercraft. The watercraft can then be easily floated into position over the carrier for retrieval.     In one embodiment, the wheels are open so that water freely flows into the wheels. The large-surface wheels are typically constructed of a heavy-duty, dense plastic or metal and have a cylindrical rim and a disk or a number of spokes extending perpendicularly inward from the rim with gussets to the cylindrical surface.  The carrier also includes rails that can be extended with a tongue-and-groove construction to accommodate longer watercraft, or multiple watercraft, on one carrier.

Abstract: This invention provides methods of obtaining novel polynucleotides and encod ed polypeptides by the use of non-stochastic methods of directed evolution (DirectEvolutionTM). A particular advantage of exonuclease-mediated reassemb ly methods is the ability to reassemble nucleic acid strands that would otherwi se be problematic to chimerize. Exonuclease-mediated reassembly methods can be used in combination with other mutagenesis methods provided herein. These methods include non-stochastic polynucleotide site-saturation mutagenesis (Gene Site Saturation MutagenesisTM) and non-stochastic polynucleotide reassembly (GeneReassemblyTM). This invention provides methods of obtaining novel enzymes that have optimized physical and/or biological properties. Through use of the claimed methods, genetic vaccines, enzymes, small molecules, and other desirable molecules can be evolved towards desirable properties. For example, vaccine vectors can be obtained that exhibit increased efficacy for use as genetic vaccines. Vectors obtained by using th e methods can have, for example, enhanced antigen expression, increased uptake  into a cell, increased stability in a cell, ability to tailor an immune response, and the like. Furthermore, this invention provides methods of obtaining a variety of novel biologically active molecules, in the fields of  antibiotics, pharmacotherapeutics, and transgenic traits.
